A little small but still fit my Foxhound, Boxer mix. A bit of a challenge to take off. Definitely recommend whatever size you think you should get, go up one more especially if you have medium to large dogs that love to play dress up!These are just a smidge big on my teacup Yorkie 3.5 lbs. But she's always cold & these help keep her warm, especially in Midwest winter! Wash up nicely. I cuffed the legs so they'd fit her better. Wish they had more styles & variety of colors than they do. Pretty true to size.These pajamas are absolutely adorable and they fit like a glove. So soft and the buffalo print is so cute for winter days. I have a 13lb Shihtzu and I purchased a medium, fits great!15” back, bought an L size, fitted perfectly. We loved it, will buy another one.Very happy with this purchase. Our 6m old 10.5 lb American Hairless fits a size large with growing room.I returned because it did not fit my dog.Cute. Nice qualityI love the doggy pajamas, but my Brody looked like a stuffed sausage,too small, I ordered a medium in another style and it was too large,the delivery was fast,thank you Amazon.check the sizing chart closely, i went by weight instead, it fits but king baggy, it would be nice to be able to adjust the neck a little bit, its really wide witch result in my cat getting out of it the second she lays down. otherwise its well made, really soft and comfortable... and really cute!!Washes really well and is super easy to put on and take offCutest little onesie for my Yorkie! Great quality no concernsUn poco más chico de lo que era
